Have you already used TiddlyWiki ? It is an awesome way to create To Do lists but I do not have an iPhone around to test it. Could you please access http://www.tiddlywiki.com/ and do some fast editing/saving ? I believe it is not possible to save any edits on the iPhone but that's what I am not sure at this point. This would give me another reason to get an iPhone by the end of this month. Thanks, M.
